Struct JsNullable

pub struct JsNullable<T>(/* private fields */);

Implementations

impl<T> JsNullable<T>

where T: JsCast,

pub fn from_nonnull(value: T) -> JsNullable<T>

pub fn from_nonnull_ref(value: &T) -> &JsNullable<T>

pub fn unwrap(self) -> T

pub fn unwrap_ref(&self) -> &T

Methods from Deref<Target = JsValue>

pub fn browser(&self) -> &Browser

pub fn retrieve_json(&self) -> RetrieveFuture<'_, Value>

Retrive this value from the JS side to the Rust side. Returns Future whose output is a serde_json::Value.

use wsdom::dom::Browser

use wsdom::dom::HTMLInputElement;

async fn example(input: &HTMLInputElement) { let _val = input.get_value().retrieve_json().await; }

Trait Implementations

impl<T> AsRef<JsNullable<T>> for JsNullable<T>

fn as_ref(&self) -> &JsNullable<T>

Converts this type into a shared reference of the (usually inferred) input type.

impl<T> AsRef<JsValue> for JsNullable<T>

fn as_ref(&self) -> &JsValue

Converts this type into a shared reference of the (usually inferred) input type.

impl<T> Clone for JsNullable<T>

where T: Clone,

fn clone(&self) -> JsNullable<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Deref for JsNullable<T>

type Target = JsValue
